SOUND-DEADENINAG WALL FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 612,733, dated October18, 1898.

Application filed April 9, 1898. Serial No. 677,016. (No model.) l

To all whom it may concern:

Be it known that I, EUGENE HENRI KELLY, a citizen of the United States,residing at Buffalo, in the county of Erie and State ofNeW York, haveinvented certain new and useful Improvements in Sound-Deadenin g Vallsfor Buildings; and-I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Myinvention relates to the science of accus* tics, and has for its'object the preparation of walls and ceilings of buildings to absorb thesound-waves; and it consists in certain improvements in constructionwhich will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a front elevation, partly in section, of myinvention; Fig. 2, a vertical transverse section; Fig. 3, a frontelevation, partly in section, of a modified construction; and Fig. 4, avertical transverse section of the same.

Reference being had to the drawings and the letters thereon, A indicatesthe permanent wall of a building; B, porous terra-cotta hollow tiles,which maybe embedded in the wall in the course of construction, or theymay be secured thereafter by any suitable means and form a foundation orbase upon which the remaining parts of the dead wall are constructed,and also by virtue of its porosity forms a sound-absorbing body orstratum in the structure.

C are metallic laths, in this instance V- shaped in transverse section,but any other form may be used. The laths are spaced about twelve inchesapart and secured to the foundation by staples o or by nails.

I) indicates wirecloth,.preferably galvanized and of about three-eighthsof an inch mesh and is secured to the laths E indicates a stratum ofclosely-packed mineral wool or asbestos fiber, in this instance placedbetween the foundation and the wirecloth, iilling the space.

F indicates a layer or stratum of heavy unbleached factory-cloth whichis stretched taut across the wire and secured in any suitable manner, asby nails extending into the foundation.

Gr indicates the finished surface, which is formed by painting orcoating the layer F and applying short fiber, l such as asbestos orclipped `wool,` thereto `by an air-blast while the paint is fresh,randforms a surface from one -sixth to one -fourth0 of an inch thick whichthe sound-waves readily penetrate and are absorbed thereby. Thisconstruction is especially designed for Iireproof structures and newbuildings.

In Figs. 3 and 4 I have shown a modification of this construction. Hindicates the wall, to which are secured strips I, of wood, about oneinch square and set about twelve inches apart and securedfby nails toform a foundation. K indicates `the wire cloth, which is secured to thestrips I, and upon the wire-.cloth is secured a stratum L of heavybuilding deadening-felt, and M indicates the iinished surface directlyupon the felt and is ofthe same material and -made in the same manner asthe surface G in Figs. l and 2.

The sound-deadening wall forms a lining to the wall of the building witha velvet or floss-like surface,- which may be of any color or designdesired and produces a ,pleasin g eect to the eye.

Having thus fully described my invention, what I claim is- 1. Asound-deadening wall, consisting of a stratum of fibrous materialsecured to the permanent wall out of contact therewith and an outersound-absorbing surface of floss-like fibrous material.

2. A sound-deadening wall, consisting of a stratum of brous materialsecured to the permanent wall out of contact therewith, a layer ofwire-cloth and an outer sound-absorbing surface secured by an adhesivesubstance.

3. A sound-deadeningwall, consisting of a stratum of fibrous material, asupport therefor, an outer soundabsorbing fibrous surface and means forsecuring the same to a permanent wall.

4. A sound-deadening wall, consisting of a foundation of porousterra-cotta, a stratum of fibrous material, a layer of `wire-cloth, anouter sound-absorbing surface and means for securing the same to apermanent wall.

In testimony whereof I ax my signature in presence of two witnesses.

EUGENE HENRI KELLY.
